Peers attest only coherent mechanism essays, so a whisper farm of templates earns nothing. To farm a haven of payouts an attacker must generate distinct, high-quality answers for every fake identity every epoch—paying continuous model inference and human review time that grows linearly with sybil count while failed grades yield zero emission.","stamp":12,"from":"poa1E62Mhd34Cr4VG4kVBewiZ5rYFVb1M5uLixJ2V7LZ9QEp","nonce":5,"parents":["81e3084c041c3f1e34c6b52a7bf6eaa2ef6928d104e865b0283378ab8e6573c5","4f53a54464b919dd25a04207a341e9b7342fe97ccfad6f56b1e974766ca1482d"],"ts":1793207093,"cid":"poa-mainnet-1","sig":"4PSpCnGkFUpMaZy1cWxsdYkFWQMqJqjGPUEEXGxFnsNwaQfUMufAWJKtfugGJUNBxsYCqJiCHGa47ikotqPoF23a"},"checkpointed":{"height":233214,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T05:55:58.603Z","checkpoint_height":233214,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
